Specification of Letters Patent. Application ala July 22, 1910. Serial no. 573,298.
Patented July 4, 1911.-
To all whom it may concern: I I
Be itknown that I, HENDRIK MAURIT VAN WEEDE, subject of the Queen of the Netherlands, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Boats, of which the following is a specification.
My invention relates to racing and other boats of the hydroplane class, in which I have provided for an air containing space' Figure 1 represents a top or plan view of the boat; Fig. 2 is a side elevation; and Figs. '3 to '13. inclusive represent sections taken on lines indicated-in Fig. 2; said lines corresponding with the numbers of the figures of said sections. Fig. 14 shows a horizontal section of a part-of the keel taken-above the plane of thev fins .H. These numerous secf tionsare given in the drawings in order to show exactly the shape of the bottom of the boat, assuming that the precise shape concerns essentially the easiest displacement of the water in the movement of the 'boat, and
particularly in reference to the mass of air constantly contained in the bottom cavity, whereby the frictional resistance is materially lessened. I have sought by thesesections to define this shape, and refer hereinafter to these sectional drawings as showing more exactly than possible by written description, the shape 'in-which this feature of my said invention consists.
The main part of the structure of the boat consists of a shell in the form of an elongated archA, the crown of which is inclined from bow to stern (as shown in Fig. 2 by the line connected with A, and in deta l in'Figs- 3 to 13, inclusive), combined with lateral hydroplanes B, B. These planes B, B may be of any desired width, adapted to. the spread anddepth of the arch .and the weight ofthe materials of the boat, and approximately its intended load, it being designed that'the lanes shall move on or near the surface 0 c-jthe water, and, if desired, their forward ends may be upturned.
The forward .end of the. arch is shown with a curved under-cut, but this is not material and may be changed. The larger end of this arch being forward, is exposed to and takes in the air as the boat advances,
and as the space beneath or within this arch regularly diminishes to the stern, or termlnates near the stern, according'to the load on the boat, the contained air is always under more or less pressure, varymg with thespeed, and this compressed air 1s interposed between the arch and the water, and
these parts and the planes andload be ing properly adjusted, the planes move practically over the surface, with greatly diminished bearing thereon, the load being largely supported by the arch. i
Centrally and suitably fixed to the arch is a main keel C having a curved lower edge, approximately as shown. Included or fixed within this keel is a tubular bearing 15 for the shaft 16 of the propeller D, which is inclined to bring its forward end up to "the motor E, of any suitable type.
. The rudder F, with any suitable or well known steering gear, steering wheel G direc ly aft of the motor, so that the boatman, as he lies or sits, may
be in position to control both rudder wheel and motor.
It is important in connection with the arch and planes that the vertical position or movement of the boat should be adjustable;
ps connected to the that is to say, that it shall be capable of bea ing lifted or depressed, and so held at will of the boatman. To this end I have provided horizontal fins, H, H, pivoted to the keel,
forward of the longitudinal center of the boat. To -lessen resistance these are narrow forward, and have bosses by which they are pivoted 0nhorizontal pins on the keel. They are controlled by stiif, vertical rods K, K, which are connected by bell crank levers L, L, to levers M, M, located in reach of the boatman. These levers are provided with ordinary lockingsegments and catches (not shown). Obviously ,both fins may be raisedor lowered, or one may be raised and the other lowered, and so to raise or lower the forward part of the boat, or to keep it trimmed;
On each side above the planes I have -rovided air tubes for floating the boat. T ese may extend part or all the way from bow to stern. As shown in the sectional figures, I have also provided supplemental keels 17 which, as arranged, are continuations of the shell of the arch and containing the cavity therein.
By the termv tapering applied to the boat, I refer to the crown of the cavity, the plan of the boat being approximately of equal width throughout. This is a material point, in my boat that the crown of the arch slopes downward from bow to stern, while the sides are parallel throughout, so that the interior channel is of the same width and varies in depth. Thus the body of the hull of the boat 1s an elongated'arch, from how to stern, the crown of which is the top or deck indicated by the straight line on Fig. 2 connected to the letter A. p
I claim substantially as described:
1. A boat, the hull of which is wholly composed of a shell forming an arch open at the bow and stern and having its crown sloping downward from bow to stern, and
I with side hydroplanes extending horizontally from the side edges of said shell and a central keel, substantially as described. 2. A boat the main part of which is wholly composed of a shell forming an arch open at the bow and stern and of equal width from bow to stern but having its crown sloping downward from bow to stern.
3. A boat the main part of which is wholly composed of a shell forming an arch open at the bow and stern and of equalwidth from bow to stern but having its crown sloping downward from bow to stern with the side hydroplanes fixed thereto and with a central keel.
4. A boat the main part of which is wholly composed of a central arch open at the bow and stern and inclined from bow to stern, combineu with side' hydroplanes, with suitable keels, and with air tubes arranged on each side above theplanes.
5. A boat the main part of which is com posed of a central arch open at the bow and stern and inclined from bow to stern, having side hydroplanes combinedwith a central keel, and with horizontally arranged fins pivoted to the keel and provided with mechanism Within the reach of the boatman for operating said fins.
In testimony whereof, I affix my signature in presence of two witnesses.
